The Vite build emitted path-absolute asset URLs (base: '/'). index.html
entry scripts and the favicon were rewritten to include the reverse-proxy
prefix in serveIndex, but two reference kinds are not in index.html and so
bypassed that rewrite:
- CSS `url()` font references (e.g. Font Awesome .woff2), which the browser
resolves relative to the stylesheet and which `<base href>` never affects
- lazily-imported route chunks, whose preload base came from the absolute
Vite base
Under a subpath mount (X-Forwarded-Prefix: /llm/) both were fetched from the
origin root, 404ing — missing-glyph "tofu" icons and broken lazy-loaded pages.
Switch Vite to a relative base ('./') so every generated URL resolves against
the file that references it: CSS fonts and route chunks now load from
`/llm/assets/...`, and index.html's now-relative entry refs resolve via the
`<base href>` serveIndex already injects on every response. Root deployments
are unaffected. The existing path-absolute rewrite in app.go still covers the
public `/favicon.svg`.

The weekly "Dependabot Updates" pip job for /backend/python/diffusers has been
failing with `private_source_authentication_failure` against the Jetson pip
index (https://pypi.jetson-ai-lab.io/jp6/cu129/), referenced by that backend's
requirements-l4t12.txt. diffusers is the only dependabot-configured pip
directory that pulls from that private index, so it is the only update job that
fails; the other backends update cleanly.
torch and transformers are deliberately pinned in this backend for
reproducibility (see backend/python/diffusers/requirements-*.txt and #9979), so
we do not want dependabot bumping them anyway. Ignoring both dependencies for
this directory stops dependabot from resolving them against the unreachable
Jetson index and keeps the weekly update job green, without removing update
coverage for the rest of the backend's dependencies.

The managed-artifact materializer stages a HuggingFace snapshot into a
directory (.artifacts/huggingface/<key>/snapshot/). That is the right load
target for directory-consuming backends (transformers, vLLM, diffusers, ...),
but PrimaryArtifactSpec inferred a managed artifact from ANY HuggingFace-shaped
model reference regardless of backend. A single-file backend such as llama.cpp
or whisper was therefore handed the snapshot directory instead of the weight
file and failed to load it.
The /import-model importer already guards this with a backend allow-list
(managedArtifactBackends), but the loader-side inference did not. Move the
allow-list into core/config as IsManagedArtifactBackend and apply it in
PrimaryArtifactSpec: only directory-consuming backends may have an artifact
inferred from a bare reference; every other backend stays on the legacy
download-to-file path. An explicit artifacts: block still bypasses the gate,
where single-file snapshot resolution handles the load path.
The importer now shares the same predicate, so both paths agree on which
backends auto-materialize.

fix(model-artifacts): load single-file HF snapshots from the file, not the dir
The managed Hugging Face artifact materializer (#10825) always pointed
backends at the snapshot *directory*
(.artifacts/huggingface/<key>/snapshot). For a single-file model
reference such as huggingface://nomic-ai/nomic-embed-text-v1.5-GGUF/nomic-embed-text-v1.5.f16.gguf,
the GGUF lives *inside* that directory, so llama.cpp was handed a
directory and failed with "gguf_init_from_reader: failed to read magic".
This has kept the tests-aio job red on master since the feature merged
(the embeddings e2e tests could not load text-embedding-ada-002).
Record the single file of a one-file snapshot as Resolved.PrimaryFile and
have ModelFileName() resolve to snapshot/<PrimaryFile> when it is set.
Multi-file snapshots (e.g. transformers repos consumed as a directory)
keep pointing at the snapshot directory. PrimaryFile is derived from the
resolved contents and is deliberately excluded from the artifact cache
key. estimateModelSizeBytes now derives the snapshot directory from the
cache key instead of ModelFileName(), so its manifest lookup is unaffected
by the file-vs-directory resolution.

The artifact progress bridge mapped every PhaseVerifying event to a flat
95%. The materializer emits PhaseVerifying once per file (from each file's
AfterDownload hook) and downloads run sequentially, so the first small file
to finish pinned the bar at 95% - and, because progress is monotonic, it
stayed at 95% for the entire remaining download (e.g. a 70GB checkpoint
reporting 95% at 410MB / 69.7GB).
Track per-file verify proportionally to the running aggregate bytes, the
same way downloading does. CurrentBytes already reflects "completed files +
this file", so the percentage advances honestly. The flat 95%/99% is now
reserved for the genuinely once-per-install Committing/Persisting phases.

The Operate → Traces "API Traces" panel already recorded who made each
request (user_id/user_name) but never showed it, and did not capture the
caller's network identity at all. Operators asked to see the requesting
user (#10886) and the client IP + user agent (#10887) so a trace can be
attributed to who/what issued it.
Backend: add ClientIP and UserAgent to APIExchange and populate them from
echo's c.RealIP() (honours X-Forwarded-For / X-Real-IP behind a trusted
proxy) and the request's User-Agent header. Both are omitempty and the
/api/traces swagger response is map[string]any, so this is additive.
UI: add a sortable "User" column to the API traces table and a metadata
block (User / Client IP / User Agent) at the top of the expanded row
detail. Fields render only when present, so older buffered traces and
unauthenticated/local requests degrade cleanly.

One agent turn runs several internal LLM generations (tool selection,

chore(moss-transcribe-cpp): bump pin to CUDA K-quant embed fix
Bumps the moss-transcribe.cpp pin to 190a569c, which merges the
host-side embed-lookup fallback for K-quant token_embd tensors
(localai-org/moss-transcribe.cpp#2).
Before this, running a q5_K/q4_K/q6_K moss-transcribe GGUF on CUDA
(or any non-CPU backend) aborted in getrows.cu with
"unsupported src0 type: q5_K" because ggml's GET_ROWS op has no
K-quant implementation on GPU, killing the backend process on the
first request. The engine now dequantizes the needed rows on the
host when the backend cannot run GET_ROWS for the tensor type,
producing bit-identical results.

Google shipped the Gemma 4 MTP drafter heads and llama.cpp merged native
support in ggml-org/llama.cpp#23398. LocalAI's pinned llama.cpp already
carries it, and the config plumbing (draft_model + core/config/mtp.go)
was built for exactly this path, but no official Gemma 4 gallery entry
wired it up.
Add llama.cpp draft-mtp speculative-decoding variants for the dense
sizes, sourced from the unsloth QAT GGUF repos (target UD-Q4_K_XL +
mtp-*.gguf drafter + BF16 mmproj):
- gemma-4-e2b-it-qat-mtp
- gemma-4-e4b-it-qat-mtp
- gemma-4-12b-it-qat-mtp
- gemma-4-31b-it-qat-mtp
These replace the previously commented-out attempts, which were disabled
because the Janvitos/boxwrench drafter GGUFs declared the architecture as
`gemma4_assistant` (underscore) and failed to load on stock llama.cpp.
The unsloth drafters use the upstream `gemma4-assistant` (hyphen) spelling
that mtp.go's isDraftOnlyAssistantArch expects, so they load without any
backend patch. The 26B-A4B MoE is intentionally omitted (the upstream PR
reports no meaningful MTP speedup for it).
Also fix gemmable-4-12b-mtp: it loaded the draft-only `-mtp` GGUF as the
main model with no draft_model set, which cannot run standalone. It now
loads the target as the model, wires the drafter via draft_model, enables
spec_type:draft-mtp, and downloads both files.
All sha256 pins were taken from the HuggingFace API lfs.oid (reliable
content hash even for Xet-backed repos).

Extend the existing talk-llama sed workaround to also rewrite the

standalone and as a subproject. The submodule itself is already checked
out by the recursive submodule init. Verified locally: the exact CI error

The turboquant and bonsai backends copy backend/cpp/llama-cpp/ wholesale
into their build directories and reuse its Makefile/prepare.sh against
their own llama.cpp forks. When PR #10837 added
backend/cpp/llama-cpp/patches/0001-add-minimax-m3-support.patch, the
copied patches/ directory was mis-applied to the fork checkouts: the
fork trees diverge from upstream, hunks rejected, and because the
patch-apply loop in prepare.sh ran before set -e took effect the build
kept going and died much later with a confusing compile error
("'LLM_ARCH_MINIMAX_M3' was not declared in this scope"). This broke
tests-turboquant-grpc on that PR.
Two hardening changes:
- turboquant/bonsai Makefiles: delete the copied patches/ directory
right after the cp -rf of backend/cpp/llama-cpp/. Patches vendored
for upstream llama.cpp must never be applied to the forks; each fork
carries its own patch series under backend/cpp/<backend>/patches/,
applied by its apply-patches.sh.
- llama-cpp prepare.sh: run the patch-apply loop under set -e so a
rejecting patch fails fast and loudly at apply time instead of
surfacing as a downstream compile error. A missing or empty patches/
directory remains a no-op success, so all existing callers (the
llama-cpp Makefile targets and the turboquant/bonsai copies) are
unaffected when no patches ship.

The gRPC configuration table only listed the two fields with a one-line
description each, without defaults, without explaining what the total
load window looks like, and without hinting when a user should adjust
them. In practice the default 20 attempts x 2 s = 40 s window is way
too tight for large NVFP4 / FP8 models on slow storage or first-run
CUDA-graph capture, and the resulting kill (exitCode=120, 'context
canceled') looks like a backend crash even though the backend is still
making legitimate forward progress.
Extend the section with:
- Defaults column (20 and 2) added to the table
- Prose explaining that these govern the readiness handshake between
LocalAI and a freshly spawned backend (Health polling loop)
- Total-load-window formula
- Concrete failure signature so users can recognize a timeout-kill
vs. a real backend crash
- Example configuration for a ~10 min cold-load window (grpc.attempts
140, attempts_sleep_time 5), with a note that inference-timeouts and
the watchdog are unaffected.
The sglang Python backend inherits the default Status RPC from
backend_pb2_grpc.BackendServicer, which raises NotImplementedError.
LocalAI's backend-monitor polls /backend.Backend/Status periodically on
every registered backend; when the call fails, /backend/monitor returns
HTTP 500 and downstream inference requests to the sglang backend are
blocked even though the model is loaded and answering directly via the
gRPC endpoint.
Add a minimal Status shim that mirrors the existing Health method and
returns StatusResponse{state=READY} unconditionally. This unblocks the
monitor path; a state-aware follow-up (UNINITIALIZED during load, BUSY
under active inference) is left for a subsequent change.
Reproduced on DGX Spark (GB10, arm64-l4t-cuda-13 image) with the sglang
v0.5.15 backend and Qwen3-Coder-Next-NVFP4-GB10; verified locally that
patching the shim in place immediately restores /backend/monitor and
inference across the sglang slot.
* fix(audio-transform): serialize WebSocket writes to avoid concurrent-write panic
AudioTransformStreamEndpoint writes to the same Gorilla WebSocket connection
from two goroutines: the backend-forwarding goroutine emits binary PCM frames
(and can call sendWSError on a backend recv error), while the read loop calls
sendWSError for malformed mid-stream JSON or a backend send failure. Gorilla
WebSocket permits only one concurrent writer, so these writers race and can
panic with "concurrent write to websocket connection", resetting the client
session; a -race build reports the data race directly.
Wrap the connection in a lockedConn that serializes WriteMessage behind a
mutex, mirroring the existing lockedConn used by the openresponses WebSocket
endpoint. Reads stay on the single read loop, so only writes need the lock.

When the watchdog's busy-killer decides a backend has been busy past the
busy timeout, it shuts it down via ModelLoader.ShutdownModel -> deleteProcess,
which grabs ml.mu and then waits for IsBusy() to clear BEFORE stopping the
process. But a backend that exceeds the busy timeout is, by definition,
stuck on an in-flight gRPC call, so the graceful wait never returns, ml.mu
is held forever, and every other ml.Load blocks — including the shared
opus backend load at the start of every realtime (WebRTC) session. New
realtime connections then hang at "Connected, waiting for session..."
whenever the watchdog is enabled, while logs repeatedly print the
watchdog's busy / "active connection" line.
Fix: add a force shutdown path (ShutdownModelForce / deleteProcess(s,
force=true)) that stops the process FIRST — dropping the stuck call's
gRPC connection and unblocking it — instead of waiting on it. Route the
watchdog's busy-killer and busy LRU / group / memory evictions through
the force path; keep the graceful wait for idle and user-initulated
unloads. Graceful/unforced kills are unchanged.
Regression test: the watchdog busy-killer uses ShutdownModelForce.

feat(bonsai): add PrismML llama.cpp fork backend + Bonsai gallery models
Adds a new `bonsai` backend that runs the PrismML fork of llama.cpp
(github.com/PrismML-Eng/llama.cpp, `prism` branch), which ships the Q1_0
(1-bit) and Q2_0 (ternary / 1.58-bit) weight-quantization kernels used by the
Bonsai and Ternary-Bonsai models. Stock llama.cpp cannot decode these quants.
Modeled on the turboquant backend: reuses backend/cpp/llama-cpp/grpc-server.cpp
against the fork's libllama via a thin wrapper Makefile, so the sub-2-bit models
are served with the same OpenAI-compatible API. No grpc-server allow-list patch
is needed (bonsai adds weight quants, transparent to the server, not KV-cache
types), and the reused server compiles cleanly against the fork with no skew
patches (validated locally via a CPU docker build; patches/ is present but empty
for any future re-pin skew).
Backend wiring: backend/cpp/bonsai/, .docker/bonsai-compile.sh,
backend/Dockerfile.bonsai, top-level Makefile targets, backend-matrix.yml build
rows (CPU, CUDA 12/13, L4T, SYCL f32/f16, Vulkan, ROCm/hipblas), backend/index.yaml
meta-backend + per-platform images, and a nightly bump_deps entry tracking the
`prism` branch.
Gallery: 8 entries across 4 families - bonsai-8b-1bit, ternary-bonsai-8b (+g64,
+pq2), bonsai-27b-1bit (vision), ternary-bonsai-27b (+pq2, +g64, vision). The 27B
models wire the mmproj vision tower; the DSpark speculative drafter GGUFs are not
wired (custom semi-autoregressive drafter, not a standard llama.cpp draft model).
